Janus Borner, Thorsten Burmester
BACKGROUND: Contaminations from various exogenous sources are a common problem in next-generation sequencing. Another possible source of contaminating DNA are endogenous parasites. On the one hand, undiscovered contaminations of animal sequence assemblies may lead to erroneous interpretation of data; on the other hand, when identified, parasite-derived sequences may provide a valuable source of information. RESULTS: Here we show that sequences deriving from apicomplexan parasites can be found in many animal genome and transcriptome projects, which in most cases derived from an infection of the sequenced host specimen...

The genera Babesia and Theileria (phylum Apicomplexa, order Piroplasmida) are mainly transmitted by Ixodid ticks in which the sexual part of their life cycle followed by sporogony takes place. They include protozoan parasites that infect erythrocytes of a variety of vertebrate hosts, including domestic and wild animals, with some Babesia spp. also infecting humans. Babesia sporozoites transmitted in the tick's saliva during the bloodmeal directly infect erythrocytes, where they asexually multiply to produce pear-shaped merozoites in the process of merogony; whereas a pre-erythrocytic schizogonic life stage in leukocytes is found in Theileria and precedes merogony in the erythrocytes...

In this study, a novel Babesia sp. infecting goats was detected and its phylogenetic relationship to related species was determined. A total of 200 blood samples collected from sheep (n=78) and goats (n=122) were examined in the study. The V4 hypervariable region of the 18S rRNA gene of the novel Babesia sp. was amplified by PCR and analysed using a reverse line blot hybridization assay adapted for small ruminants. Samples from seven goats hybridized to Theileria/Babesia catch-all and Babesia catch-all probes and did not hybridize to any species-specific probe tested, suggesting the presence of an unrecognized Babesia species or genotype...

Equine piroplasmosis (EP) is a hemoprotozoan tick-borne disease with worldwide distribution that is caused by Theileria equi and Babesia caballi. There are studies reporting the presence of equine piroplasmosis in Turkey but the situation in Erzurum is unknown. The aim of the current study was to determine the situation of equine piroplasmosis in jeered horses in Erzurum. Between April and August 2015, a total of 125 Arabian horse were examined and blood samples were collected. At the time of sampling, animals were also examined for tick infestations and clinical signs...

A loop-mediated isothermal amplification (LAMP) assay was evaluated for the detection of Theileria annulata infection in cattle. The results were compared with a real-time PCR used for the quantification of T. annulata parasitaemia. One hundred bovine blood samples from 16 cattle farms were tested with LAMP and real-time PCR, with T. annulata DNA being detected in 66% and 67% of the samples, respectively. The results showed that the LAMP assay detects a parasitaemia as low as 0.00025%, indicating a high analytical sensitivity of LAMP for clinical diagnosis of bovine theileriosis...

Ticks are important vectors of emerging and re-emerging zoonoses, the majority of which originate from wildlife. In recent times, this has become a global public health concern that necessitates surveillance of both known and unknown tick-borne pathogens likely to be future disease threats, as well as their tick vectors. We carried out a survey of the diversity of ticks and tick-borne pathogens in Kenya's Shimba Hills National Reserve (SHNR), an area with intensified human-livestock-wildlife interactions, where we collected 4297 questing ticks (209 adult ticks, 586 nymphs and 3502 larvae)...

Ticks are able to transmit various pathogens-viruses, bacteria, and parasites-to their host during feeding. Several molecular epidemiological surveys have been performed to evaluate the risk of tick-borne pathogens in China, but little is known about pathogens circulating in ticks from eastern China. Therefore, this study aimed to investigate the presence of bacteria and parasites in ticks collected from Xuzhou, a 11258km(2) region in eastern China. In the present study, ticks were collected from domestic goats and grasses in urban districts of Xuzhou region from June 2015 to July 2016...

Bovine theileriosis, a tick-borne protozoan disease caused by Theileria annulata, Theileria orientalis and Theileria sinensis, is widespread in China and is a serious economic problem for the Chinese livestock industry. In this study, recombinant major piroplasma surface proteins (MPSP) of T. annulata, T. orientalis and T. sinensis based on MPSP genes were expressed in Escherichia coli BL21(DE3). The immunogenicity and specificity of the three purified recombinant MPSP proteins were evaluated with the reference positive sera of T...

Enterohaemorrhagic E. coli (EHEC) and enteropathogenic E. coli (EPEC) are enteric bacterial pathogens of worldwide importance. Most EPEC and non-O157 EHEC strains express lymphostatin (also known as LifA), a chromosomally-encoded 365 kDa protein. We previously demonstrated that lymphostatin is a putative glycosyltransferase that is important in intestinal colonisation of cattle by EHEC serogroup O5, O111 and O26 strains. However, the nature and consequences of the interaction between lymphostatin and immune cells from the bovine host are ill-defined...

Ixodes scapularis, the black-legged tick, is one of the most common human-disease vectors and transmits Borrelia species, such as B. burgdorferi, as well as Theileria microti, Anaplasma phagocytophilum, etc. As basic helix-loop-helix (bHLH) transcription factors have been recognized for many years as important regulators of various developmental processes, we performed phylogenetic analysis of the black-legged tick genome in order to identify the number and family of bHLH transcription factors. Because bHLH family members have been identified in many organisms, including silkworm and fruit fly, we were able to conduct this survey and identify 58 putative bHLH transcription factors...

The Southeast region of Portugal, particularly the Guadiana valley, is currently the reintroduction territory of Lynx pardinus (Iberian lynx), one of the most endangered felids in the world that is only found in the Iberian Peninsula. Over the last century, populations have declined, placing L. pardinus at extremely high risk of extinction in the wild and relying on reintroduction projects. Among the aspects taken into account in the establishment of new populations is the sanitary status of the selected habitats, especially concerning infectious diseases, including tick-borne pathogens (TBPs)...

Infiltration and proliferation of Theileria parva infected lymphocytes in bovine host lymphoid organs is one of the hallmarks of T. parva infection. The relative abundance of parasites within infected host tissues, both lymphoid and non-lymphoid is however unknown. Using quantitative PCR, we have shown that significantly higher concentrations of T. parva DNA are detected in the spleens of cattle undergoing severe disease compared to other organs.

Infection with Babesia and Theileria Causes high mortality and economical losses in livestock and has a relatively high prevalence in Iran. In Zabol, animals are susceptible to this disease because of presence of vector ticks, weather conditions and smuggle animal across the border and they cause great damages to the economy and production. However, few studies have been done for differentiation of Theileria and Babesia in sheep in this area. The purpose of the present study was to determine the prevalence of Babesiosis and Theileriosis in sheep in Zabol...
